故事:
    友人在折腾[http://www.openldap.org/ LDAP] ,使用Python 的 [http://twistedmatrix.com/ Twisted] 组件来开发时应用常常死亡，
    怀疑Python的内存泄露，但是找不到证据……
结局:
    找到高人[http://blog.delphij.net/ delphj] 运用内存分析工具:
{{{
/usr/ports/devel/valgrind> cat pkg-descr
Valgrind is a system for debugging and profiling un*x programs. With the tools
that come with Valgrind, you can automatically detect many memory management
and threading bugs, avoiding hours of frustrating bug-hunting, making your
programs more stable. You can also perform detailed profiling, to speed up and
reduce memory use of your programs.

The Valgrind distribution includes five tools: two memory error detectors, a
thread error detector, a cache profiler and a heap profiler. Several other
tools have been built with Valgrind.

Valgrind was ported to FreeBSD by Doug Rabson (http://www.rabson.org/).

    才发现是[http://www.openldap.org/ LDAP]本身的问题：
    每次RPC 的远程连接结束后，会泄露 32字节的内存！
    晕哪！怪不得叫 LDAP, 因为很轻的连接情况下的确很不容易发觉，在当前内存动不动就上Gb的情况下…………

    '''Python的虚拟机是非常坚固的！不要轻易怀疑吧……'''
